Title: Semiconductor device and manufacture thereof
Inventor: TAKATANI SHINICHIRO
IPC: H01L29/73
Filed: 1995-06-12
Abstract: PURPOSE: To prevent the increase of a leakage current by a method wherein a nitride layer, which is mainly composed of a III-group element nitride, is formed continuously on both of the interface of the semiconductor of the lower part of a gate electrode and the III-V semiconductor surface between the gate electrode and a source/drain low resistance region. CONSTITUTION: A pattern 2, consisting of an insulating film and a resist film, etc., is formed on a III-V compound semiconductor 1. Then, using the pattern 2 as a mask, the compound semiconductor 1 is etched to the desired depth by conducting reactive ion-etching on the compound semiconductor 1 by plasma using a halogen element. Then, a nitride layer 3 is formed on the etched surface. On the surface which is etched using a halogen element, as the vapor pressure of the V-group element halogenide is higher than the halogenide of III-V group element, the III group element becomes excessive, and a III-group compound is mainly formed when the surface is nitrided. As the nitride of the III-group element is more stable than the nitride of the V-group element, a chemically stable surface can be obtained.

Abstract: PURPOSE: To control the inlet steam of a low-pressure turbine to protect turbine blades from overstressing and overheating, by introducing reheating steam of high temperature and pressure into a reheater from the downstream side of a steam regulating valve for main steam.  
     CONSTITUTION: Discharged steam from a high-pressure turbine 2 is dried by a moisture separator 3 and heated again by a reheater 4. Steam from a low-pressure turbine 6 is changed into water by a steam condenser 6. Some of steam downstream to a steam regulating valve 9 is introduced into the reheater 4 through a passage 11 equipped with a control valve 10, thereby reheating the steam discharged from the high-pressure turbine 2. Load control is effected by a steam regulating valve 9 so that the inlet pressure and outlet pressure of the high-pressure turbine 2 are almost proportional to the load. The temperature at the inlet port of the low-pressure turbine 6 is thus controlled to protect the turbine 6 from thermal fatigue and overheating.
